The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to pro- mote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, the Office for Information Programs, and the Office of Experimental Technology Incentives Program. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consist- ent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essen- tial services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce. The Institute consists of the Office of Measurement Services, and the following center and divisions: Applied Mathematics — Electricity — Mechanics

  • Useful Forestry Measurements Acre: a Unit of Area Equaling 43,560
    Useful Forestry Measurements Acre: A unit of area equaling 43,560 square feet or 10 square chains. Basal Area: The area, usually in square feet, of the cross-section of a tree stem near its base, generally at breast height and inclusive of bark. The basal area per acre measurement gives you some idea of crowding of trees in a stand. Board Foot: A unit of area for measuring lumber equaling 12 inches by 12 inches by 1 inch. Chain: A unit of length. A surveyor’s chain equals 66 feet or 1/80-mile. Cord: A pile of stacked wood measuring 4 feet by 4 feet by 8 feet when originally conceived. Cubic Foot: A unit of volume measure, wood equivalent to a solid cube that measures 12 inches by 12 inches by 12 inches or 1,728 cubic inches. Cunit: A volume of wood measuring 3 feet and 1-1/2 inches by 4 feet by 8 feet and containing 100 solid cubic feet of wood. D.B.H. (diameter breast height): The measurement of a tree’s diameter at 4-1/2 feet above the ground line. M.B.F. (thousand board feet): A unit of measure containing 1,000 board feet. Section: A unit of area containing 640 acres or one square mile. Square Foot: A unit of area equaling 144 square inches. Township: A unit of land area covering 23,040 acres or 36 sections. Equations Cords per acre (based on 10 Basal Area Factor (BAF) angle gauge) (# of 8 ft sticks + # of trees)/(2 x # plots) Based on 10 Basal Area Factor Angle Gauge Example: (217+30)/(2 x 5) = 24.7 cords/acre BF per acre ((# of 8 ft logs + # of trees)/(2 x # plots)) x 500 Bd ft Example: (((150x2)+30)/(2x5))x500 = 9000 BF/acre or

    Imperial units From Wikipedia, the free encyclopedia Jump to: navigation, search This article is about the post-1824 measures used in the British Empire and countries in the British sphere of influence. For the units used in England before 1824, see English units. For the system of weight, see Avoirdupois. For United States customary units, see Customary units . Imperial units or the imperial system is a system of units, first defined in the British Weights and Measures Act of 1824, later refined (until 1959) and reduced. The system came into official use across the British Empire. By the late 20th century most nations of the former empire had officially adopted the metric system as their main system of measurement.

Although most of the units are defined in more than one system, some subsidiary units were used to a much greater extent, or for different purposes, in one area rather than the other. The distinctions between these systems are often not drawn precisely.

  • Dimensions and Units English Units of Measurement Units of Weight
    English units of measurement Today: A system of weights and measures used in a few nations, the only major industrial one Chapter 6 continued: being the United States. It actually consists of Dimensions and Units two related systems—the U.S. Customary System of units, used in the United States and dependencies, and the British Imperial System. Units of Weight The pound (lb) is the basic unit of weight (which is proportional to mass) (how?). Within the English units of measurement there are three different systems of weights. In the avoirdupois system, the most widely used of Question: the three, the pound is divided into 16 ounces (oz) and the ounce into 16 drams. The ton, used Is there a problem? to measure large masses, is equal to 2,000 lb (short ton) or 2,240 lb (long ton). In Great Britain the stone, equal to 14 lb, is also used. “weight is proportional to mass.” Answer: You need to be aware of Force = Mass* Acceleration the law governing that proportionality: Newton’s Law Acceleration is NOT a constant, mass is. Force = Mass* Acceleration Even on earth, g = 9.81 m/s2 is NOT constant, but varies with latitude and Question: elevation. Is there a problem? “weight is proportional to mass.” “weight is proportional to mass.” 1 Another problem arises from the A mass is NEVER a “weight”. common intermingling of the terms “mass” and “weight”, as in: Force = Mass* Acceleration “How much does a pound of mass weigh?” Or: “If you don’t know whether it’s pound- “Weight” = Force mass or pound-weight, simply say pounds.” “Weight” = Force Forces in SI Units …because on earth all masses are 2 exposed to gravity.
